SEEDING-MACHINE.-

SPECIFICATION forming part of Letters Patent! No. 257,622, dated May9,1882.

Application filed August 30, 1881. (Model.) 7

To all whom it may concern:

Be it known that we, JOHN W. SO N, CHARLES O. RICHTER, and ROBERT S.CARR, of Hamilton, Butler county,Ohio,have invent- 5 ed certain new anduseful Improvements in Seeding-Machines, of which the following is aspeeification,reference being had to the accompanying drawings, inwhich- Figure l is a side view, partly in section, of 1 our improvedseeder; Fig. 2, a perspective view of one of the shovels Fig. 3, aperspective view of one of the seed-tubes, and Fig. 4a plan of liftingmechanism. This invention pertains to improvements on theseeding-machine patented June 22, 1875, by Jos. R.Sy1nme's,thepatentbeiugnumbered 164,781, and reference should be had to said patentin connection with this specification. Where no detailed descriptionofparts is herein made such parts are to be considered as beingconstructed in accordance with said patent or in accordance with custom.

In Fig. 1, H is the framing, G the wheel,

\V the axle, m the tongue, B the seed-box, A the fertilizer-box, D thedropping-hose, O

O the conduits thereto from the boxes, E the distributors, L theshovels, V the drag-bars,

I the winch-bar, M N the lifting-chains, J the winch-lever, and K thewinch-lever hook, of a seeding-machine.

Fertilizer'and seed both pass through the distributersE. Thesedistributors are hollow castings attached to their drag-bars. They havea broad bottom and beveled front. They are supported close to theground, but donot touch the soil, except in case they strike clods,whichit is their function to remove sidewise. They drop the seed andfertilizer upon the level surface of the soil, which is to have beenprevious- 0 ly pulverized and prepared. The shovels L follow behind andbetween the distrilouters and cover the seed-bed with soil removed frombetween the seed-beds, thus producing alternate ridges and furrows witha level broad 5 seed-bed containing seed and fertilizer across the ridgebelow its upper surface. The shovels L are'triangular, with a bevelcrowned face, as shown in Fig. 2, the side edges being straight and theangle acute. The curvature of the shovto the shanks.

els is vertical only, as shown in Fig. 1, all other coutour'lines beingstraight ones. This form of shovel possesses maximum efficiency as-a.covering-shovel when set well in the soil, and

. when set lightly in the soil its acute poiutforms a most perfectcultivator-tooth for the aftertreatment of the ridged crop. The shovelsL are of chilled cast-iron, and have thin rear-jaws, b, which clasp theside of the shank a. The shovels are cast on the shanks, and holes 0,previously cut in the shank, permit metal to join the two flanges andrigidly dowel the shovels The rear surface of the shank, not beingcovered by the cast-iron, is exposed, and tends to remain cool duringthe process of casting, and thus insure a lesser shrinkage of the shank;This securesa rigid union of the parts.

*The winch-bar 1- serves, as usual, to lift the shovels by means ofchains M. The dist-ributers E are lifted by chains N. The chainsN areattached to the winch-bar at a point nearer its axis than are the chainsM, and the distributers are thus lifted alesser distance. As thedistributers are set much higher than the shovels they need but a slightlift, and the power to lift is thus reduced.

In addition to the hand-lift, a device is provided for automaticallylifting the dragging parts. i I

The pulley O is fast on the winch-bar l. The pulley P. is loose on theaxle W. The chain Q transmits motion between these two pulleys. Thepulley P has clutches It upon its face.

S is a clutch splined upon the axle W, and arranged to be thrown intogear bythele'ver T. 8 5

U is an incline, fixed to the frame of the maehine,which at acertainpointobstructs the rotation of the clutch S and throws said clutch outof gear withthe pulley P. At the unclutchingpoint the winch;bar is atits extreme up- 0 ward position and the drag-work is lifted. When theclutch uncouples, the hook K catches the lever J and sustains the parts.The dragwork is lowered by hand, as usual, and when down is ready at alltimes to be lifted by power 5 by the simple manipulation of the lever'1.

As the pulleys O and 1? make but partial revolution, it is obvious thatthey may be segmental, and that a single chain fastened to the peripheryof each segment will serve instead of the belt-like chainshown in thedrawings.

The clutch-work may be applied at the axis of the winch-bar, its pulleybeing the loose one in such case, without departing from the spirit ofthis invention. Other forms of clutches and disengaging devices may alsobe employed.

We claim as our invention- 1. In a seed-drill of the class specified,the distributing-tubes E, having abroadened and flattened issue end, Iwith beveled front surfaces, substantially as shown and described.

2. The combination of distributors having broadened ends arrangedtoscrape the surface of the soil,seed-conduits and fertilizer-conduits,both set to issueinto said distributers, and corering-shovels arrangedbehind and between said distributers to produce unfertilized trenchesbetween the seed-rows, substantially as shown and described.

3. In a seed-drill of the class specified, the combinatiomwithseed-distributing tubes havingbroadened, flattened,and beveled issueend, of following coveringshovels in the form of an acute triangle withstraightside edges and hereled crowning faces, substantially assetforth.

4. The combination,with a shovel-shank having its end perforated, of ashovel cast thereon andhaving rearflanges clasping said shank and unitedby the metal in said perforations, substantially as set forth.

I 5. The combination of shovel-shank a with shovel L, cast thereon,having flanges b in contact with the shank, the shovel and flangesconsaid distribnter attached to said winch-bar at a point nearer itsaxis than the point of attachment of said shovel-chain, substantially asset forth.

7. The combination of a main axle, a'winchbar parallel thereto, a seriesof drag-bars suspended from the winch-bar and arranged to be lifted bythe rotation of the same, a means for transmittingrotary motion fromtheaxle to the winch-bar, a sliding clutch and fixed incline orequivalent device for arresting such transmission, a lever projectingfrom the winch-bar, a hook to engage said lever and retain'it whenmotion is arrested, and a lever for starting the transmission,substantially as set forth.

8. The combination, with a seeder-axle, a rotary winch-bar, a winch-barlever, and its retaining-hook, of a tight pulley, a loose pulley, ameans of'transmission between them, a sliding clutch adapted to engagewith said loose pulley, a hand-lever to slide said clutch, and a fixedincline to release said clutch, substantially as set forth.
